Also, you wish to ignore facts and reasoning posted by economists all in the name of "disruption". And FYI The Planning Commission of India AKA "Policy Pundits" consists of renowned economists.
Forget the Planning Commission of India, we have had the worst experience with a Prime Minister, who was an Economist, and had no spine to take on the corrupt or even implement his own policies. India practically lost 10 years of it's growth to this useless economist. So no please, we don't need more economists. We have more than enough Economists. We need someone who can take tough policy decisions.
As I said earlier, economists have a place. He was great as a Finance Minister and RBI Governor. But the moment he became a policy decision maker (rather than just a policy maker) he failed miserably. Do you understand this basic difference? This is the reason I say that economists cannot take policy decisions. They can make the right policies if they are dictated by someone higher up the chain but are incapable to take the same decisions if they are given a chance.
The evidence for that is the GST reform. GST was the brainchild of Manmohan Singh and his Planning Commission when he was the Prime Minister for 10 years. But he failed to get the damn reform passed in the Indian Parliament mainly because he did not know or understand political maneuvering. How is it that the same GST reform, which was Manmohan's brainchild, passed by Narendra Modi (who is his opponent) without any troubles?
